First let's convert the time in seconds:

The current is defined as the quantity of charge flowing through a certain section of a circuit per unit of time:

Using I=10 A, and

, we can find the amount of charge flown through the hair dryer in this time:

The charge of a single electron is

, so the number of electrons flown through the hair dryer is the total charge divided by the charge of a single electron:
Answer:
Decreases
Explanation:
When an electron is released from rest in a region of space with nonzero electric field. And when the electrons move the electric potential energy of the system decreases because the kinetic energy increases and for the total energy to remain constant the potential energy must reduce.
An electron is accelerated in an electric field meaning its kinetic energy increases.
Answer:
None.
Explanation:
- By definition, work is a process that it happens when an applied force
causes an object to change its position, i.e. to have a displacement.
Since the laptop cart is at rest while he stops at the water fountain, no
net work done is on the laptop cart.
(a)The window panes are transparent
(b)The colors of the panes are due to the wavelengths of light that the glass allows to pass through.
<h3>What are trasparent glasses?</h3>
The glasses which allows the light rays to pass through them are called as the transparent glasses.
or visible light is electromagnetic radiation within the portion of the electromagnetic spectrum that is perceived by the human eye.[1] Visible light is usually defined as having wavelengths in the range of 400–700 nanometres (nm),
corresponding to frequencies of 750-420 terahertz, between the infrared (with longer wavelengths) and the ultraviolet (with shorter wavelengths
Hence the window panes are transparent the colors of the panes are due to the wavelengths of light that the glass allows to pass through.

Use direct proportionality: If 1.25 m = 72 N, then 0.55 m = y
0.55 m × 72 = 39.6.
39.6÷1,25 gives you your answer which is 31.68 N.
